Plate tectonics

3. molten rock under the surface
5. the top layer of rocks on the Earth, the crust and the uppermost mantle
8. a boundary between tectonic plates or a weak spot on a plate, where earthquakes occur and the relative position of the ground changes
12. All of the living things on Earth
14. rock formed from layers of dirt, silt or sand
16. rock rock that has been changed without completely melting by high temperature and pressure
17. type of fault where the plates move towards each other
20. type of rock formed from cooled molten rock
21. exact point where an earthquake originated (under the ground)
22. the middle layer of molten hot rock of the Earth

1. type of fault where the ground separates
2. the solid layer on the outside of the Earth
4. All the rocks and minerals, molten and solid, making up the Earth
6. All of the gases surrounding the Earth
7. type of fault where two plates moves along each other in opposite directions
9. tectonics study of the movement of the Earth’s crust as a series of large slabs moving in different directions
10. molten rock that has erupted onto the surface
11. one plate moves under another
13. point on the ground where an earthquake originated
15. the movement of magma into other layers of rock
18. centre of the Earth, extremely hot and dense with high iron content
19. the bending of rock into anticlines and synclines as the rock gets compressed
